create_box

create_box: function(x_min, y_min, x_max, y_max)

Description

Creates an instance of type box at the desired spatial coordinates.
The instance defaults to the current label the user has selected.

The function uses check_reasonableness and will warn if the instance is not reasonable (eg has negative values).

Example

JavaScript

diffgram.create_box(0,0,100,100)

Example - Conversion

For example from using coco-ssd
They state that they have bbox: [x, y, width, height]. Here we convert width to x_max by doing width - x

JavaScript

diffgram.create_box(
  prediction.bbox[0],
  prediction.bbox[1],
  prediction.bbox[2] + prediction.bbox[0],
  prediction.bbox[3] + prediction.bbox[1])     
}

Warnings

Instance not reasonable

Errors

Must have x_min, y_min, x_max, y_max
